<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a connection structure capable of improving conduction reliability between electrodes. <P>SOLUTION: A manufacturing method of a connection structure 1 according to the invention includes steps of: placing an anisotropic conductive material layer using anisotropic conductive material including conductive particles 5 on a first connection target member 2 having an electrode 2a on its top surface 2; changing the anisotropic conductive material layer to a B-stage by radiating light or heat from the top surface of the anisotropic conductive material to promote curing of the anisotropic conductive material layer; laminating a second connection target member 4 having an electrode 4b on its undersurface 4a on the top surface of the anisotropic conductive material layer of the B-stage; and forming a cured material layer 3 by curing the anisotropic conductive material layer of the B-stage. The degree of cure of the cured material layer 3 is made different between the cured material layer part 3a on the first connection target member 2 side and the cured material layer part 3b on the second connection target member 4 side. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
